The e-Framework Reference Model for Assessment (FREMA) project has developed two Service Usage Models (SUMs). Summative On-line Assessment has many existing tools within this space, while Peer Review is a less well supported area. A distinction may be made between Peer Review, the marking of a studentâs work by their peers, and Peer Assessment, the marking of collaborative group work by a tutor (which may be modified by peer reflection). Peer Review is an important tool for giving feedback to large student cohorts when tutor time is limited, and is also an important learning activity in its own right. This project will undertake the development of an initial set of services from the Peer Review FREMA usecase, providing lightweight REST services, which may be reused within other group-oriented SUMs, to support the resource submission and distribution phases of Peer Review.
